Are there any grammar mistakes in the line below?
The displacement of a ship sailing 8 km from P to Q on a bearing of 75° is denoted
by PQ and represented by the directed line segment shown in the figure below.
Should it be "sailing" or "sailed"?
I presume 'directed line segment' is some correct mathematical/vector/trigonometical term.
I can't see any grammatical errors.
